Answer 1

2m 20cm + 1m 60cm =​   3 m 80 cm

Step-by-step explanation:

2m 20cm + 1m 60cm =​

= (2 +  1)  m  (20 + 60) cm

= 3 m 80 cm

Using 1 m = 100 cm

2 m 20  cm  = 2 * 100 + 20  = 220 cm

1 m 60 cm = 1 * 100 + 60  = 160 cm

220 + 160  = 380  cm

= 380 /100  m

= 3.8 m

= 3   + 0.8 m

= 3  m +  0.8 * 100 cm

= 3m + 80 cm
